9 p.m. June 12, Lifetime Ally Walker has played layered, compelling characters in FX's "Sons of Anarchy" and in NBC's "Profiler," making her one of those actresses you just can't ignore. But not even she can keep my interest in "The Protector," in which she plays L.A. homicide detective Gloria Sheppard, a taskmaster who angers her co-workers by doggedly pursuing her hunches. The added twist that she's a single mom gives the show it's Lifetime-required touchy-feely vibe, but otherwise, the show offers nothing more than any other light police procedural of the summer does. Walker deserves better. Pictured: Ally Walker (left) and Tisha Campbell-Martin (right).
